Sydney Scientists Recreate Cosmic Dust to Probe Origins of Life

Researchers at the University of Sydney have recreated cosmic dust in a laboratory to study life’s origins.
The dust mimics material formed around dying stars and later delivered to Earth by meteorites.
It contains organic CHON molecules, key chemical building blocks of life.
PhD researcher Linda Losurdo produced the dust using plasma created inside a vacuum chamber.
Scientists hope the work explains how meteorites gained organic matter before reaching Earth.
Experts say the technique could support future experiments on early life formation.
The study appears in the Astrophysical Journal.
